Air quality is of utmost importance in environmental studies and has many industrial applications such as aviatorsí grade breathing oxygen (ABO) for pilots and breathing air for fire fighters. Contamination is a major concern for these industries as identified in MIL-PRF-27210, CGA G-4.3, CGA G-7.1, and NFPA 1989. Fourier Transform Infrared Spectroscopy (FTIR) is a powerful tool that when combined with a gas cell has tremendous potential for gas contamination analysis. Current procedures focus mostly on GC-MS for contamination quantification. Introduction of this topic will be done through a comparison of the currently used deterministic methods for gas contamination with those of FTIR gas analysis. Certification of the mentioned standards through the ISO/IEC 17025 certifying body AIHA will be addressed followed by an evaluation of quality information such as the determinations of linearity, the limits of detection and quantitation, bias, and uncertainty. Major interferences and issues arising from the use of the FTIR for accredited work with ABO and breathing air will be covered.
